Nice solution with the spread operator! I see a lot of katas on codewars that require this sort of thing.

What I have to do if want to get a new array with [Mary, Anna] ?

[rickyu]

looking forward to the next tutorial on comparison objects or array of objects . I was able to solve my array problem by using a filter (stole from stackoverflow)
I find it way to complicated to read, but it does work, the new filteredArray does not have duplicate properties that match the element.name

Could you do a tutorial on findIndex and find?

const filteredArray = totalArray.filter((element, index, array) => {
return (index === array.findIndex(function(t) {
return t.name === element.name;
})
);
});

This video is under the regular expression playlist.
But in complete video,
No single use of regular expression.

Pls make sure that, playlist should contain related videos.
